An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles

open access: yesIntegrative Zoology, EarlyView.
We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

THE INFLUENCE OF DISCONTINUITIES ON ROCK MASS QUALITY AND OVERALL STABILITY OF ANDESITE ROCK SLOPE IN WEST JAVA

open access: yesRudarsko-geološko-naftni Zbornik, 2020
Open-pit mining constitutes a necessary activity for the extraction of rocks and minerals from the Earth. However, openpit mining activities often result in rock slope stability issues related to the discontinuities of rock masses.

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
